Android 14

Affected device model

TCL 505

How did you install the app?

Google Play Store

Steps to reproduce the bug

0. Go to settings
1. Export vcf using "whatsapp" as source (I've configured WA to only use local contacts, ("Sync to phone" cannot be disabled in this mode))
2. Switch to "Contacts" tab
3. Filter by "WhatsApp"
4. Select all
5. Delete

Expected behavior

It should only delete the contacts from the filtered account, or show a warning if a contact belongs to multiple accounts

Actual behavior

If any of the selected contacts is in any account other than the filtered one, it will also be deleted there.

I assume this happens because of the "Merge duplicate contacts" setting

Screenshots/Screen recordings

No response

Additional information

I've tried importing the aforementioned vcf file, only to find it only has the data that was stored in the "whatsapp" account, which is technically correct, but that doesn't fix the fact that I've lost data.
